摘要
根据谐波励磁系统的结构特点,推导出了三次谐波电势方程,而后结合电机转子运动方程、功率方程、励磁绕组电磁动态方程,建立了谐波励磁电机的非线性方程,对于励磁系统的进一步控制调节具有重要意义。结合具体电站参数,通过与普通电机的仿真对比,验证了其在保持输出电压稳定方面较强的自我调节能力。
According to the structure characteristic of harmonic excitation system, the three harmonic EMF equation was deduced. And then combined with the rotor movement equation, power equation, the excitation winding of the electro-magnetic dynamic equation, the nonlinear equation of harmonic excitation synchronous generator was established. This will have important meaning to further control of the excitation system section. Combined with the specific parameters of the power station, the strong self-adjustment ability in keeping the output voltage stable was verified by contrast with the com-mon synchronous generator.
